For instance, the Vertimill® generally uses spherical grinding media in a size range that varies from 6 to 38 mm, depending on the ore and machine [4]. Jankovic [6,7] investigated the effect of grinding media in a vertical stirred pilot mill and found that 6.8 mm steel grinding media were more effective than coarser (12 mm) grinding media ...
